Besides the second half of the second set Berdych couldn't hit a backhand down the line or even put a return back into play.
I agree that his ROS wasn't good today but overall he played ok. He wasn't great and wasn't really bad. The thing is that when these 2 play, the important points and maybe some luck here and there could decides who wins the match. Janko was better in most of the big points but also was a bit lucky (in the 1st set when Tomas got a set points and was close to win the point but linesman saved Janko). This match could have gone either way.
I just don't agree with you that Tomas was bad overall. Just one aspect of his game was bad which is his ROS. Everything else was solid. He could beat most players on the tour with this level but he lost because Janko played a good match.
